2011-09-03Allow overriding the location of Samba's smbd.Brad
Allow overriding the location of Samba's smbd. Pretty much every OS I look at has some means of changing this path (patching) so lets just make it easier for OS developers creating packages and/or end users to override the location.

2011-07-23net: Consistently use qemu_macaddr_default_if_unsetJan Kiszka
Drop the open-coded MAC assignment from net_init_nic and replace it with standard qemu_macaddr_default_if_unset which is also used by qdev. That avoid creating colliding MACs when instantiating NICs via different mechanisms. This change requires to store the MAC as MACAddr in NICInfo, and the remaining nd_table users need to be updated. Based on suggestion by Peter Maydell.

2011-07-23net: Refactor net_client_typesJan Kiszka
Position entries of net_client_types according to the corresponding values of NET_CLIENT_TYPE_*. The array size is now defined by NET_CLIENT_TYPE_MAX. This will allow to obtain entries based on type value in later patches. At this chance rename NET_CLIENT_TYPE_SLIRP to NET_CLIENT_TYPE_USER for the sake of consistency.

2011-06-22net: Warn about "-net nic" options which were ignoredPeter Maydell
Diagnose the case where the user asked for a NIC via "-net nic" but the board didn't instantiate that NIC (for example where the user asked for two NICs but the board only supports one). Note that this diagnostic doesn't apply to NICs created through -device, because those are always instantiated.

2010-10-06net: delay freeing peer host deviceMichael S. Tsirkin
With -netdev, virtio devices present offload features to guest, depending on the backend used. Thus, removing host netdev peer while guest is active leads to guest-visible inconsistency and/or crashes. As a solution, while guest (NIC) peer device exists, we prevent the host peer from being deleted. This patch does this by adding peer_deleted flag in nic state: if host device is going away while guest device is around, set this flag and keep a shell of the host device around for as long as guest device exists. The link is put down so all packets will get discarded. At the moment, management can detect that device deletion is delayed by doing info net. As a next step, we shall add commands that control hotplug/unplug without removing the device, and an event to report that guest has responded to the hotplug event. Signed-off-by: Michael S.

2010-04-10net: remove broken net_set_boot_mask() boot device validationEduardo Habkost
There are many problems with net_set_boot_mask(): 1) It is broken when using the device model instead of "-net nic". Example: $ qemu-system-x86_64 -device rtl8139,vlan=0,id=net0,mac=52:54:00:82:41:fd,bus=pci.0,addr=0x4 -net user,vlan=0,name=hostnet0 -vnc 0.0.0.0:0 -boot n Cannot boot from non-existent NIC $ 2) The mask was previously used to set which boot ROMs were supposed to be loaded, but this was changed long time ago. Now all ROM images are loaded, and SeaBIOS takes care of jumping to the right boot entry point depending on the boot settings. 3) Interpretation and validation of the boot parameter letters is done on the machine type code. Examples: PC accepts only a,b,c,d,n as valid boot device letters. mac99 accepts only a,b,c,d,e,f. As a side-effect of this change, qemu-kvm won't abort anymore if using "-boot n" on a machine with no network devices. Checking if the requested boot device is valid is now a task for the BIOS or the machine-type code.

2010-02-19net: Fix bogus "Warning: vlan 0 with no nics" with -deviceMarkus Armbruster
net_check_clients() prints this when an VLAN has host devices, but no guest devices. It uses VLANState members nb_guest_devs and nb_host_devs to keep track of these devices. However, -device does not update nb_guest_devs, only net_init_nic() does that, for -net nic. Check the VLAN clients directly, and remove the counters.
